Digital Tbucket Tank (DTT)

Science tank

Welcome to our “Science Tank” section. In this area of ​​the website, we deal with relevant discoveries from the world of science (physics, mathematics, computer science, medicine and many more) in an interdisciplinary manner. We publish important achievements from around the world with a special focus on the scientific environment in Göttingen. Have fun and stay curious.     

The 40-year-old nuclear fission puzzle solved

When an over-inflated balloon bursts, its parts fly away in opposite directions and perform various feats in the air. The process of Nuclear fission, in which a nucleus is split in two, accompanied by the emission of several neutrons, works in a similar way. The energy released in the process manifests itself not only in the form of kinetic energy of the fragments that have arisen, but also in the form of rotation and other core excitations. One of the accompanying phenomena is the emission of Gamma ray quantaNot only the surplus of the generated energy, but also the Angular momentum cancel (ie inhibit rotation).

Cosmic rays will expose the smuggling of hazardous substances

An Italian-American team led by Francesco Giggi from the University of Catania has one Muon tomograph Developed in original size that can scan shipping containers for fissile material. The researchers used two layers of Muon detectors and a special algorithm to create a 3D image of a small lead container hidden in the container.

Many goods are in containers transported around the world. Since they are large and many of them walk around the ports, it is very easy to hide a small object in them. Security experts are increasingly concerned about the risk of fissile material being smuggled in this way. Therefore, there is a need for technology that allows containers to be shipped quickly and reliably scanned without the Flow of goods to interrupt.

A little nano-origami and there is a record-breaking chip

A team of physicists from the University of Sussex in the UK published the construction of a novel in the ACS Nano Journal microchips on the basis of graphene and other single-layer materials (2D) with a record-breaking small size. As the authors explain the achievement, it was produced by "crinkling" layers of graphene in what they call Nano origami describe.

JET physicists are ready to test the fuel for the ITER tokamak

The British tokamak Joint European torus (JET) will soon start testing a fuel mix that will be used in the future ITER, the largest experimental fusion reactor in the world. Nuclear fusion is a process that takes place in the sun. Mastering them can provide mankind with a nearly inexhaustible source of clean energy.

JET is 10 times smaller than ITER. In December was there with experiments Tritium began. With this, humanity is leading for the first time since 1997 Fusion reactions with significant amounts of this element.

In June of this year tests will begin with equal amounts of tritium and deuterium are involved in the reaction. This is exactly how ITER will work so that we can get more energy out of the fusion than we put into it. Until now, humanity has not been able to generate any net energy gain from the fusion.

Video only as an example.

They created a black hole, confirmed Hawking's prediction, and observed the inner horizon

Stephen Hawking predicted that Black holes Emit radiation like a black body. This emission, known as the Hawking emission, is constant over time and its temperature is determined by the Gravity certainly. Although Hawking's prediction is 50 years old, the temperature of the radiation has not yet been confirmed by observations. It will likely be extremely low, on the nanokelvin scale or less.

Diagonal chess: Update on diagonal chess rules

Dear readers. Due to numerous inquiries and requests for a more detailed description of the Diagonal chess rules we have decided on the article "A scientist from the Cracow University of Technology developed a new kind of chess game - diagonal chess "  to write an update. 

There was already chess for three players, played on a three-sided chess board, and chess for four players, played on a chess board with 160 pieces (instead of the traditional 64). Chess games were played on 80 or 100 boards. In its day, Polish hexagonal chess pieces with hexagonal squares became popular. It seemed that everything in this field had already been invented. Zbigniew Kokosiński, lecturer at the Technical University of Cracow, however, had a completely new idea. He has that Diagonal chess designed.

Samsung built artificial intelligence into a memory chip

Samsung Electronics did the development of the first High Bandwidth Memory (HBM) announced module that is integrated with an artificial intelligence module - HBM-PIM. The Processing-in-Memory (PIM) architecture The interior of the high-performance memory modules is primarily intended for accelerating data processing in database centers, high-performance computing (HPC) systems and mobile applications.
Our HBM PIM is the first programmable PIM solutionwhich was developed for various artificial intelligence applications. We plan to expand our partnerships with providers of artificial intelligence solutions so that we can come up with more and more advanced solutions At the moment, we are already using PIM can offer said Samsung Vice President Kwangil Park.

Germans created a quantum logic gate between two qubits in two different laboratories

German researchers at the Max Planck Institute for Quantum optics have a logical Gate operation performed with two qubits located in two different laboratories. Your achievement is a very important step towards distributed quantum processing. It could allow the building of modular computer systems made up of devices that are in different places but function like one big computer. The addition of another qubits now quantum computers is not an easy task. Qubits must be able to perform logical operations and at the same time from external influences (noise) that their Quantum state can destroy, be isolated.
A very important source of noise in Quantum systems is the interference between the qubits themselves. For example, if we have a system of 4 qubits and we want to perform calculations involving only 2 of them, there is still a risk of interaction between qubitswho do not participate in the calculations.

Super fast ion tunnel

We live in a modern world full of devices that run on electricity. The development of new technologies ensures that cell phones, laptops, tablets and many other mobile devices are with us every step of the way. Lithium-ion batteries, so-called Li-ion rechargeable batteries, are most commonly used for powering mobile devices, but due to their slow charging, short service life and environmental pollution (due to the high content of heavy metals, e.g. cobalt), more and more attention is being paid to Super capacitors directed. These are devices that have properties of Batteries and capacitors combine. What is it related to? Longer service life, easier recycling and, above all, faster charging, which means time savings. After all, time is money.

Light levitation

Researchers at the University of Pennsylvania have succeeded in floating two small plastic plates with ordinary light. Using the energy from bright LEDs placed in a vacuum chamber, the researchers brought the two Miniature Mylar Sheets to float. This was seen as a breakthrough as it had never been possible to lift such large objects with light alone.


The kind of Polyesterfrom which the light Levitation plates is under the trade name Mylar known. The underside was covered with a special layer that, when heated by the light rays of the LEDs, gave off energy to the air molecules below, causing the plate to float. The achievement was described in the journal Science Advances.
